SILENT FLUSHIN G APPARATUS FOR WATER-CLOSETS R URINALS.

SPECIFICATION forming part of Letters Patent No. 645,203, dated March13, 1900.

Application filed October 1, 1898.

To all whom it may concern:

Be it known that I, JOSEPH OHALLENDER, residing at 12 Moss Lane \Vest,in the district of Moss Side, Manchester, in the county of Lancaster,England, have invented new and useful Improvements in Silent FlushingApparatus for lVater-Olosets or Urinals, (for which I have madeapplication for patent in Great Britain, No. 17,316, dated August 11,1898,) of which the following is a specification. 7

My invention relates to improvements in flushing apparatus forWater-closets and urinals, the object being to dispense with valves,siphons, or levers inside the cistern and the chain or pull, exceptingfrom choice, thus rendering the closet silent up to delivery.

My improved system of flushing water-closets and the like consists of afloat in the water-cistern which acts automatically in connection with avalve and catch inside a metal box containing said valve,which is placedin a convenient position between the water-cistern and the closet orurinal. The said valve can be opened and brought into use by a push orbutton, hereinafter described, or, if desired, by lowering or raisingthecloset-seat or by the opening or closing of a door or other mechanicalcontrivances. I attain these objects by the means illustrated in theaccompanying drawings, in which- Figure 1 is a longitudinal section ofthe water-supply cistern; Fig. 2, a vertical section, and Figs. 3 and 4tsectional plans, of the said valve-box, the latter at lines A A and B Bof Fig. 1, respectively, the valve being shown removed in Fig. 3. Fig. 5shows at a reduced scale a diagram of the whole flushing system. 7

Similar letters refer to similar parts throughout the several views.

In carrying out my invention and referring to Figs. 1, 2, 3, and A, A isthe box containing the said valve, which box may be constructed in anyshape in one or more parts-- say in two parts, as shown in Figs. 2, 3,and 4, an upper one a and a lower one a, which can be joined together byflanges or otherwise, and having an inlet 1) and outlet b sufficientlylarge for the flushing-water to pass freely. The lower part a containsan ordinary valve-seating c and a valve d, attached Serial No. 692,449.(No model.)

to a bar or swivel e, which turns easily and is kept in position by lugsor stops f. The ends of the bar or swivel c are cranked upward or somade as to'form projections c 6, adapted to' be acted upon by the forkedends g g of a rod g, connected with the button or push g which rod ismounted in a'stuffingbox 71., formed on the valve-box A. This rod andbutton are not connected with but simply lift the valve d when pushedagainst the projections e e and when released are returned to theirnormal position by a spring t'. In the upper part a, immediately overthe valve cl, but just under the inlet 1), is fulcrumed to a spindle loa catch or lover I, one side of which is weighted and the other sideopened out like a spreader or fan and slightly turned at its edge,whichwhen at rest stands out horizontally under the inlet 1) of the valve boxA. (See full lines, Fig. 2.) In connection with this valve and catch afloat m is employed in the water-cistern 41, (see Fig. 1,) large enoughto cover the orifice of the flush pipe 0, secured therein,which latteris formed with a seating 0, while the said float carries an air-tube m,projecting on, both sides and vertically guided by the bridge 0 \Vhenthe cistern n is charged with water, the float is buoyed over theflush-pipe o and kept in this position while the column of water in thepipe rests upon the valve 01 in the box.

Below the under side of the float m air-holes m are formed in theair-tube m, which permit the air accumulated above the water in theflush-pipe 0 when nearly full and the float is on its seating to escapethrough the air-tube m, so as to prevent bubbling and noise.

The operation of the system is as follows: \Vhen it is desired to flushthe water-closet p, the button g outside the valve-box A, is pressed inand immediately released, which action causes the valve cl in the box Ato be lifted into the position shown in dotted lines,

Fig. 2. The column of water in the flush-pipe nearly empty the floatcloses the orifice-of the flush-pipe 0, whereby the swirl and suckingncise usually created by the escape of Water in ordinary cisterns isobviated. When the water has left the li ush-pipe 0, the Weighted catchis freed from its pressure, and the Weight of the catch then raises itsfan end off the valve (1 and allows the same to fall and close. TheWater in the cistern n then flows slowly through the apertures q, formedin the upper end of the flush-pipe 0, into the latter, and when chargedthe float rises oif its seating 0 again.

What I claim as my invention, and desire to seoure'by Letters Patent,is-

1. In apparatus for flushing Water-closets, urinals and the like, incombination with a Water-cistern n a float m having an air-escape tube127/ formed with side holes m and a seating 0 for the latter to operateupon, the said seating having lateral holes q which permit the water torun from the cistern a into the flush-pipe 0 While the float m rests onthe seating o, all substantially as and for the purpose set forth.

2. The combination of the cistern n, the

flush-pipe o, the val ve-boX A in the flush-pipe below the cistern, thevalve d in the valve box, the valve-operating push-rod g passing" intothe said valve-box, the valve-retaining catch Z pivoted tothe interiorof the box above the valve cl, all substantially as set forth.

3. In combination, the cistern n having, a float m, the valve-box Acontaining a valve d, raised by a pusha-od g, g and retained by aweighted catch Z subjected to the action of the column of Water in theflush -pipe 0, which valve-box is inserted intothe latter, allsubstantially as and for the purpose set forth.
